Data for Ice recrystallisation inhibiting polymer nano-objects via saline-tolerant polymerisation-induced self-assembly Panagiotis G. Georgiou (5920634) Ioanna Kontopoulou (14186311) Thomas R. Congdon (6171713) Matthew I. Gibson (1273788) Biomimetics Ice crystals -- Growth Polymerization Nanocomposites (Materials) Migrated from ePrints Chemical tools to modulate ice formation/growth have great (bio)technological value, with ice binding/antifreeze proteins being exciting targets for biomimetic materials. Here we introduce polymer nanomaterials that are potent inhibitors of ice recrystallisation using polymerisation-induced self-assembly (PISA), employing a poly(vinyl alcohol) graft macromolecular chain transfer agent (macro-CTA). Crucially, engineering the core-forming block with diacetone acrylamide enabled PISA to be conducted in saline, whereas poly(2-hydroxypropyl methacrylate) cores led to coagulation. The most active particles inhibited ice growth as low as 0.5 mg mL−1, and were more active than the PVA stabiliser block alone, showing that the dense packing of this nanoparticle format enhanced activity. This provides a unique route towards colloids capable of modulating ice growth.<br><br>Data record consists of a zip data file containing 8 subfolders organised according to experiment and an index file in .txt format. All background data including example images are included. Files are in .gif, .jpeg, .tif, .txt, .csv and NMR formats. 2020-05-28T00:00:00Z Dataset Dataset 10.82444/warw.33805426.v1 https://figshare.com/articles/dataset/Data_for_Ice_recrystallisation_inhibiting_polymer_nano-objects_via_saline-tolerant_polymerisation-induced_self-assembly/33805426 CC BY 4.0
